Abstract

The photothermovoltaic effect, i.e., current and voltage generation under homogeneous heating is observed for the first time in a Si1 – xGex (0 ≤ x ≤ 1) variband continuous solid solution. In the temperature range from 25 to 80°С, currents ranging from 1.0 to 39.6 nA and voltages ranging from 0.05 to 3.8 mV are generated.
